Abstract: A thermal management cabinet for electronic equipment such as servers, having an opening in the top and bottom of the cabinet. The cabinet extends between a raised access floor of a building carrying cooled air and a drop ceiling for venting heated air. The bottom opening of the cabinet is alignable with an opening in the access floor such that cool air can pass into the cabinet and can flow through the electronic component storage area to the top opening, which is alignable with an opening in the drop ceiling. The cabinet interior is separated into temperature zones comprising at least a cold zone supplied with air from the access floor and a hot zone for venting through the top opening. At least one baffle creates the temperature zones such that air is directed to flow from the cold zone through the electronic component storage area to the hot zone.
